I got a chance to check out Allan J. Lichtman's new book White Protestant Nation: The Rise of the American Conservative Movement. Overall, it is a very solid book and I recommend it. There is one significant flaw: Lichtman underestimated Sun Myung Moon's influence. Here's Lichtman's take on Moon:
From 1971 through the fall of the Berlin Wall in 1989, the Unification Church built by far the most expansive and expensive anticommunist network in he history of the Cold War. The church likely spent more than a billion dollars on its political and related enterprises during those years. The decline of the red menace in the 1990's, however, diminished the appeal of Moon's political activities in the United States.
Actually, Moon most likely spent a lot more than a billion dollars during that period on various political activities. However, the most glaring flaw in the passage is that Moon's influence and appeal was in decline after the end of the Cold War. If anything, Moon has been amping things up since the late 1980's--as this blog and other sources have documented. Nevertheless, overall Lichtman's book is a good read and I reccommend it.
Addendum: Lichtman defends the book against critics on the right.
